To solve the problem \( 4.08 - 2.12 \), you would write it vertically as follows:
4.08
- 2.12
_______
Now, subtract the numbers starting from the rightmost column:
- Hundredths place: \( 8 - 2 = 6 \)
- Tenths place: \( 0 - 1 \) cannot be done without borrowing. So, we borrow 1 from the units place (making it 3), turning the 0 into 10. Now, \( 10 - 1 = 9 \).
- Units place: \( 3 - 2 = 1 \)
Putting it all together, the final answer is:
4.08
- 2.12
_______
1.96
So, \( 4.08 - 2.12 = 1.96 \).
